COVER-OPENER.

Application filed July 10, 1914. Serial No. 850,139.

To all whom it may concern:

Be it known that I, FRANK J. LEONARD, at Olivia, in the county of Renville and tate of Minnesota, have invented certain new and useful Improvements in Cover-Openers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to .provide an improved cover opener for boxes, cans,

and the like, having telescoped covers, wherein the opener is permanently secured to the body of the receptacle in a position to engage the cover, under a rotary movement of the opener, and thereby impart the initial opening movement to said cover.

To the above end, the invention consists of the novel devices and arrangement of parts hereinafter described and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure l is a view in side elevation, showing a box, hav-' ing applied thereto the improved cover opener, some parts being broken away, and some of the exposed parts being shown in section; Fig. 2 is a plan .view of the same; Fig. 3 is a view corresponding to Fig. 1, with the exception that the cover is partly opened by the improved opener; Fig. 4 is a detail view in plan, on an enlarged scale, of the improved opener and a portion of the box; and Fig. 5 is a transverse vertical section, taken on the line a enlarged zscale.

The numeral'l indicates the body of a metallic box, having a cover 2 telescoped 5 of Fig. 3, on an thereon. The closing movement of the cover 2 onto the body 1 is limited by an outwardly pressed annular stop bead 3, formed in the side wall of the body 1, slightly above the intermediate portion thereof.

The box illustrated in the drawings has been shown simply to give one form of receptacle to which the invention may be applied.

The improved cover opener is, as shown,

flopiea of this patent he obtained for five cents each, by addressing the Specification of Letters Patent.

.thereby prevent the cover Patented June a, 19 15.

pressed to form a convex surface which closely fits within the positions thereof.

lVhen the cover 2 is closed, as shown in Fig. 1, the turn button is in a horizontal position parallel with the loweredge of said cover and alined with the head 3. To impart the initial lifting movement to the cover 2, the turn button 1 is rotated by the finger pieces 7, which brings either of its shoulders 6, depending on which way the same is rotated, into engagement with the lower edge of said cover. The beveled shoulders 6 cause the turn button 1 to enter between the hol body 1 and cover 2 and from slipping off from the turn button during the rotation thereof. These shoulders also tend to draw the adjacent portion of the cover flange out of engagement with the body of the box and thereby assist in the opening movement of the cover.

tiirn button at all having a concave "surface fitting a spherical surface on the receptacle.

In testimony whereof I aiiix in presence of two witnesses.
